Information processing apparatus, information processing method, and information processing program

Abstract

An information processing apparatus includes a selection unit selecting at least a part of a text included in contents, an acquisition unit acquiring a processing result of natural language processing for the part of the text selected by the selection unit, a specifying unit specifying a predetermined part of the text based on the processing result acquired by the acquisition unit, a detection unit detecting a keyword from the predetermined part of the text based on the processing result acquired by the acquisition unit, a tag generation unit automatically generating a tag in accordance with the keyword detected by the detection unit, and an association unit associating the tag generated by the tag generation unit with the predetermined part of the text.

1 . An information processing apparatus comprising:
 a selection unit selecting at least a part of a text included in contents;   an acquisition unit acquiring a processing result of natural language processing for the part of the text selected by the selection unit;   a specifying unit specifying a predetermined part of the text based on the processing result acquired by the acquisition unit;   a detection unit detecting a keyword from the predetermined part of the text based on the processing result acquired by the acquisition unit;   a tag generation unit automatically generating a tag in accordance with the keyword detected by the detection unit; and   an association unit associating the tag generated by the tag generation unit with the predetermined part of the text.   
     
     
         2 . The information processing apparatus according to  claim 1 , wherein the tag generation unit generates the tag as a word expressing a meaning of a superordinate concept for the keyword. 
     
     
         3 . The information processing apparatus according to  claim 2 , further comprising:
 a classification unit classifying the predetermined part of the text based on the tag.   
     
     
         4 . The information processing apparatus according to  claim 3 , wherein the classification unit classifies the predetermined part of the text based on the tag expressing a meaning which accords with or is similar to the meaning of the superordinate concept in accordance with the meaning of the superordinate concept arbitrarily selected. 
     
     
         5 . The information processing apparatus according to  claim 4 ,
 wherein the selection unit selects the entire text,   wherein the detection unit detects the keywords from the entire text, and   wherein the classification unit classifies the keywords of which the meaning of the superordinate concept accords with or is similar to the meaning expressed by the tag among the keywords detected from the entire text together with the predetermined part of the text.   
     
     
         6 . The information processing apparatus according to  claim 4 ,
 wherein the selection unit selects the entire text, and   wherein the detection unit detects, as keywords, words of which the meaning of the superordinate concept accords with or is similar to the meaning expressed by the tag from the entire text.   
     
     
         7 . The information processing apparatus according to  claim 4 , further comprising:
 a display control unit performing control to display the predetermined part of the text;   a transmission unit transmitting the tag associated with the predetermined part of the text to an external apparatus, when the predetermined part is displayed; and   a reception unit receiving information regarding the tag which is returned from the external apparatus when the transmission unit transmits the tag,   wherein the display control unit performs the control to display both the predetermined part of the text and the information received by the reception unit.   
     
     
         8 . An information processing method comprising:
 selecting at least a part of a text included in contents;   acquiring a processing result of natural language processing for the selected part of the text;   specifying a predetermined part of the text based on the acquired processing result;   detecting a keyword from the predetermined part of the text based on the acquired processing result;   automatically generating a tag corresponding to the detected keyword; and   associating the tag with the predetermined part of the text.   
     
     
         9 . An information processing program causing a computer to execute:
 selecting at least a part of a text included in contents;   acquiring a processing result of natural language processing for the selected part of the text;   specifying a predetermined part of the text based on the acquired processing result;   detecting a keyword from the predetermined part of the text based on the acquired processing result;   automatically generating a tag corresponding to the detected keyword; and   associating the tag with the predetermined part of the text.
